HOG-HOISTING MACHINE.

Specification of Letters Patent.

Patented Oct. 11, 1910.

Application filed August 5, 1907. Serial No. 387,112.

To all whom it may concern:

Be it known that I, ALFRED HANNAFORD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hog-Hoisting Machines,of which the following is a specification.

This invention relates to improvements in hog hoisting machines, and theprimary object of the same is to provide improved means for removingshackled hogs from the pens, hoisting them and automatically deliveringthem onto an overhead track or rail at a point which is not directlyover the operator, thereby avoiding all dangerof the hog falling uponthe operator.

A further object is to provide an improved device of this characterwhich is adapted to be located between two or more pens so that the hogsmay be removed from either one or all of the pens at the same time.

A further object is to provide an improved device of this characterwhich extends substantially the entire length of the pen, whereby thehog may be drawn from any part of the pen.

A further object is to provide an improved form of link for the carrieror hoisting chain.

A further object is to provide an improved device of this characterwhich will be simple, durable and cheap in construction, and effectiveand efficient in operation.

To the attainment of these ends and the accomplishment of other new anduseful objects, as will appear, the invention consists in the featuresof novelty in the construction, combination and arrangement of theseveral parts hereinafter more fully described and claimed, and shown inthe accompanying drawings illustrating an exemplification of theinvention, and in which Figure 1 is a side elevation of an improveddevice of this character, constructed in accordance with the principlesof this invention. Fig. 2 is a side elevation of the shackle hook bymeans of which the shackle is attached to the conveyer. Fig. 3 is an endelevation of Fig. 2. Fig. 1 is a top plan view, partly broken away, ofFig. 1. Fig. 5 is a side elevation, partly in section, of the improvedform of link. Fig. 6 is a top plan view of the improved link. Fig. 7 isa detail sectional view on line 77 of Fig. 5, also showing a portion ofthe track or guideway. Fig. 8 is a rear end elevation of Fig. 1. Fig. 9is an enlarged detail view showing means for delivering the shackled hogto the overhead track.

Referring more particularly to the drawings, and in this exemplificationof the in vention, the numeral 10 designates two pens between which thisimproved carrier is lo cated. Arranged between the pens are tracks orguide-ways 11, 12, which are an ranged preferably in the same verticalplane and extend substantially the entire length of the pens. Thesetracks or guide-ways are preferably of a channel formation, the track orguide-way 11 being located preferably adjacent the floor of the pen andin such a position that the open side thereof will be directeddownwardly while the track or guide-way 12 is located above and spacedfrom the track or guide way 11, and 1s arranged so that the open portionthereof will extend upwardly or in a direction opposed to the directionof the track or guide-way 11. These tracks or guide-ways 11, 12, arepreferably inclined as shown, and the extremity of the track orguide-way 12 is inclined upwardly as at 13, and extends for somedistance above the top of the pens, as shown more clearly in Fig. 1 ofthe drawings. The upper end of the inclined portion 13 may be held inposition in any desired or suitable manner, preferably by means of asupport 14 and a brace 15, one end of which is secured to the track orguide-way 13, and the other end to a suitable overhead beam 16. A pulleyor sprocket wheel 17 is journaled adjacent the end of the track or guideway 13, and located between the ends of the tracks or guide-ways 11 and12 in the pens is a suitable sprocket or pulley wheel 18, which latteris mounted in adjustable bearings 19, controlled by means of a suitableadjusting screw 20. A similar sprocket wheel 21 is journaled in asuitable support adjacent the end of the pens remote from the pulley orsprocket wheel 18, and at a point substantially below the pulley orsprocket wheel 17. Passing around the sprockets or pulley wheels 17, 18and 21 is an endless chain or belt, designated generally by thereference number 22, and said 12, and extend over the top edges thereofto hold the chain or belt 22 in the tracks or guide ways and againstdisplacement by any strain which may be exerted thereon by the hog whenthe shackle is attached to the chain 22.

Motion may be imparted to the chain or belt 22 in any desired orsuitable manner, preferably by means of a gear wheel 24,

which is secured to the sprocket wheel 21,

portmg tracks commonly known as the stickwhich in turn receivesmotionfrom a suit able pinion 25 on the power shaft 26, which latter isrotated by means of the pulley 27 in the ordinary and well knownnranner. The chain or belt 22 is adapted to move in the directionindicated by the arrows in Fig. 1 of the drawings, and the tracks orguide-ways 11 and 12 and the extremity 13 of the track or guide-way 12are so arranged that the run ofthe chain or belt between the sprocketsor pulley wheels 17, 21, will be the only portion exposed andunprotected, and is the portion of the chain which has passed out ofoperative position, as will be described. I

The chain 22 is provided with specially constructed links shown moreclearly in Figs. 5 and 7 of the drawings, and said links are arrangedthroughout the entire length of the chain and suitably spaced from eachother. These links comprise a body portion 28, which is provided withapertures or recesses 29 adapted to receive the extremities of theadjacent links of the chain, said extremities being secured to the linksby means of suitable pivots30 which pass through the body portion 28 andthe adjacentextremitie's of the links. A suitable fralne-work 31 issecured to the body portion'28- by means of projections 32, 33, and isspaced from the top of the link, as shown more clearly in Figs. 5 and 7of the drawings, and the projections 32, 33, are of such a length thatwhen the body portion 28' of the link moves within the tracks orguide-ways, the frame-work 31 will project above the top thereof, theprojections 32, 33 being of such a width as to pass between theextremities'of the L'shaped members 23 when the body portion is in theguide-way,

' a as shown more clearly in Fig. 7 of the drawings; If desired, thebody portion-28 of the link may be provided with inclined or beveledsides 34,'as shown more clearly in Fig. 7 of the drawings, in order toconform to the inclined face of the sides of the tracks or guide-ways.The frame-work 31 is preferably of a length substantially equal to thelength of the body portion 28, and is of a hook shaped formation, thenose 35 of the hook extending for some distance above the body portionof the frame-work 31, with the throat 36 thereof opening in or towardthe fere with the movement of the chain when the special link isadjacent any of the sprocket wheels.

The numeral 37 designates overhead suping track, by means of which thehog is conveyed into the sticking room. These tracks 37 may be supportedin any desired or suitable manner, preferably by means of adj ust ablehangers 38 engaging the tracks and the beam 16. The forward ends ofthese tracks are located adjacent the sprocket wheel 17 and arepreferably provided with a downwardly curved extremity 39, whichpreferably conforms to the contour of the sprocket or pulley wheel 17and terminates adjacent the upper extremity of the inclined portion 13of the track or guide-way 12, as shown more clearly in Figs. 1 and 9 ofthe drawings.

Secured to one extremity of the shackle chain 40 is a hook d1 which isprovided with a smaller hook 42 projecting from the opposite edgethereof, as shown more clearly in Fig. 2 of the drawings.

In operation, a hog is shackled in the ordinary manner around one of itshind legs by means of the shackle chain 40. After the hog is shackled,the hook is carried to the conveyer or hoisting chain 22, which latteris continuously moving, and the shackler engages the frame-work 31 ofthe link 28 with the small hook 42 within the pen holding the hook inengagement with the frame-work a sufficient length of time to cause thetwo to be securely connected, or until the conveyer or hoisting chainhas advanced a suflicient distance to place a tension on the shacklechain and draw the hog in the pen toward the upwardly inclined portion13 of the track or guide-way 12. hen the shackler first places the hook42 in engagement with the frame-work 31 of the link 28, it will assumethe position as shown at A in Fig. 1 of the drawings, and as the hog isdrawn forward by the advancement of the conveyor or hoisting chain, thehook 42 will ride on the'side of the framework 31 toward the throat 36of the hookshaped portion and the connecting portion on the front end ofthe framework which forms the nose 35 thereof will prevent the hook 42from disengaging from the framework 31. As the hog is elevated by meansof the chain or belt 22, the shackle will assume the position as shownat B in Fig. I of the drawings; the hook 12 resting in the throat 36 ofthe frame-work, which will prevent the shackle from becoming disengagedfrom the frame-work 31 by any jarring action caused by the motions ofthe hog. The hog being thus attached to the conveying and hoistingmechanism, will be raised upwardly in the direction of or toward thetracks 37, and as the body portion 28 of the link to which the shackleis attached emerges from the extremity of the inclined portion 13 of thetrack or guide-way 12, the hook 41 will pass over the downwardly curvedextremities 39 of the respective tracks 37, and as the shackle isfurther raised to the highest point of the conveyer or hoisting chain22, the hook all will move into engagement with or along the tracks 37,and as the link 28 starts to descend, the framework 31 will pass out ofengagement with the hook 42 and allow the hook tl to remain hanging uponthe track 37, after which the shackle with its supported hog may bemoved along the track to any desired point, as shown at G in Fig. 1 ofthe drawings. This operation is contlnued until the pen is emptied, andby arranging the conveyer and hoisting chain between two or more pens,the hogs may be supplied to the conveyer or hoisting mechanism from bothpens, thereby more rapidly supplying or conveying the hogs to thesticking room.

If desired, the tension of the conveyer and hoisting chain 22 may bevaried by means of the adjusting screws 20.

With this improved construction it will be noted that the hogs areshackled and conveyed along the pen to a point remote from the shacklerbefore being elevated, and that they will be elevated and deposited uponan overhead track also at a point remote from the operator, therebyobviating or avoiding the danger of the hog falling upon the operator.The only portion of the conveyer or hoisting chain which is exposed is aportion of the return run after it has deposited the shackle upon theoverhead track. It will also be noted that by extending a portion of theconveyer or hoisting chain for some dis tance within the pen, theshackler will have sufficient time to securely engage the link with thehook before the hog is raised or elevated from the floor of the pen,thereby also obviating the danger of the hog disengaging the hook fromthe link or falling back into the pen.

In order that the invention might be fully understood by those skilledin the art, the details of the foregoing embodiment thereof have beenthus specifically described, but

\Vhat I claim as new and desire to secure by Letters Patent, is
